33 kV出线地埋电缆中间接头爆裂的原因分析

Cause Analysis of the Burst of the Intermediate Joint of 33 kV Outgoing Buried Cable

随着社会经济的不断发展,对电力输送质量要求也在提高,其中电缆接头是电缆线路中绝缘结构相对薄弱、容易发生故障的节点。以Ferk变电站33 kV出线地埋电缆中间接头爆裂为例进行故障分析,并就故障原因提出改进措施,为有关人员提供一些有益的借鉴。

With the continuous development of social economy,the requirements for power transmission quality are also improving,among which cable joints are nodes with relatively weak insulation structure and easy to fail in cable routes.Taking the explosion of the intermediate joint of 33 kV outgoing buried cable in Ferk substation as an example,the fault analysis is carried out.Improvement measures are proposed on the cause of the failure.The research in this paper provides some useful lessons for those involved.
